FRANeoIs HILAIN, or LYON, FRANCE.-

"auToNioBiLEJ" Beitknownthat I, FRAN'ors PILAIN, conn structor, acitizenv of the French'Republi'c,

and a resident of 17 Chemin de Montplaisir, Lyon, France, have inventeda certain 'new and useful Live-Axle for Automobile Vehi-` cles HavingSplayed Wheels, of whichv the viollowin is a ull, clear, andexactdescription, an for which I have applied for Letters Patent. in France,dated October 26, 1904.,

- gle. In present -..day' automobile carriages having live-axle drive itis impossible to obtain this splaying because the two parts of the reallive-axlewhich'extend from one side 'and the other of the differentialor balanceear located inthe balance-gear box of the atterare journaledor provided with bear-- ings in the cylindrical casing which isfa'st tothe gear-box aforesaid andl attached tol the springs of the vehicle.This construction renders impossible the obtaining of even a very slightamount of splay, inasmuch as the wheel is fixed to 4the journaled axleand can onl be at right angles thereto; New itis preferaiile in order toobtain the utmost efficiency to have s layed road-wheels. My invention4enables t is splaying to be obtained, and in addition it insuresperfect or at least improvedconditions of transmission without abnormalbinding or irition, 'such as occurs in rdinary live-axles.

the vehicle, accordi-ng to the lWell-known arrangernent.-v f

The foregoing arrangement is considered only as an example and as beingthe one most generally adopted;`but Athe invention is not limitedthereto, and the transmission of the engine-p ower .to the' differentialed by any desired method.

. Thev tubular bridge A is ended atlits extremities by two parts a a,slightly inclined relatively to the main body A oi' the bridge in lsucha manner that the axes Y of theseiftwo inclined parts u, make a smallangle with the axis X of the axle; Upon the slantedvv extreniities la.of the .fixed tubular .bridge are. mounted theroad-wheels C by meansotplain or ball bearings. f

ing B, roceedthe two sha ts or arts of the live-ax e E E, which extendinsi e the whole length of the tubular bridge A and exceed. it at itsextremities Without making contact therewith and Without the use ofbearingrings. These two parts of the axle E E are connected to theroad-wheels C C by means,rk of any suitable joint or articulationdevice,. and this'latter may consist of a cardan ioint.v or any otherjoint arrangement whichallows' two axes which are set a connectionbetween at an angle.

This device effects the connection between the end e of the axle and theouter cap c of the hub or nave ofthe wheel. In the example illustratedthe connecting device is comi posed of a spherical segment F, centeredin the cap c and having u on its bases two slots or notches at rightangies one to the other. With one fof these latter there engages v theT'- shapd' head orfend e ofthe axle and with the placed in the cas- Iother there engages a web c', belonging to the cap ofthe' whee hub. Itwill therefore be understood vthat `this spherical segment F efiects aconnection between the horizontal axle E and the road-wheel C o'r' whichthe axis makes'a small angle with this axle.

tial by being simply lengaged thereto 1 by means of ay pair of keys d d.To dismount the parts, it'is suicient to remove the wheel- The two`lparts of the axleare connected to the difierenca s and to draw out thetwo parts of the ax e. y

.The connection between the live-axle and the road-wheels may beeffected by any jointed device which allows power to be transmitted fromthe horizontal axis of the laxle tothe road-wheels placed obliquely-tosaid horizon- IIO tal axis, and in such manner that these roadwheels aredriven from their outer caps.

Having thus described my invention, what I claim as such, and desire tosecure by Letters Patent, is-

'A live-axle having flared or splayed wheels for automobile vehicles, inwhich the outer tubular body or bridge is slanted or inclined at its twoextremities'torming two parts which make a slight angle with the mainbody of the bridge and upon which are mounted the road wheels, the axesof which are thus slightly oblique relatively to the axis of the axle,the live-axle proper located in th'e tubu- 'lar bridge extendinghorizontally for the whole ofthe length of the latterto beyondV itsextremities without makingr contact with the bridge and withoutbearing-rings, boing connected only at one end to the*differential andat theother to the road-wheels, the con-
